Yeah, my '94 SB F-150 has dual tanks. Well, had, the rear tank has been discontinued. It kinda needed them too. I think the rear tank is like 11 gallons and the front is maybe 13 or 14 gallons. You don't go to far between fillups without both functioning when your only getting about 15 mpg with a worn out 302.Just about every fullsize from 80-96/7 had dual tanks, they were decently common on 77-79s to. 73-76s generally had suicide tanks.
Dual fuel tanks on rangers were pretty uncommon, ive only seen a couple, and i believe 88 was the last year.
